Whatever you do, just don't come off as a slut to people, it's just what idiotic sex-driven teenagers think is "in".
I agree with >>46
A lot of college guys are just in it for the sex, so you need to get to know a person first. My ex was a complete mystery and seemed like a "..." person. But once i went to his house for a party, and he turned out to be a very loud gamer... so looks can be very very decieving!
You could pull of a Densha Otoko, i'm sure the lot of us here are willing to advise you :3
